The RG makes indentations on either side of the groove once installed which significantly increases its holding power. It can also be installed directly against the face of the retained part virtually eliminating end play. Automated installation using a Rock Kick Jr. pneumatic installation tool is recommended (Note; this product works only on "soft" shafts)
